Development of the Earthquake Anxiety Scale: Validity and Reliability Study

In this study, it was aimed to develop a new, valid and reliable measurement tool to measure general earthquake anxiety (EAS). For this purpose, firstly, the literature on earthquake was reviewed and an item pool was created. Then, two separate samples were taken for EFA and CFA. In order to determine the factor structure of the measurement tool, EFA was applied on the data obtained from the first sample group and a structure with 2 factors and 13 items was reached. In order to test the accuracy of this structure, data were collected from a different sample group and CFA was applied on these data. The results revealed that the scale has evidence of construct validity, discriminant validity and internal consistency reliability. In addition, earthquake anxiety scale items can be used to assess anxiety levels in different age groups.

Psychometric Properties of the Detachment and Compartmentalization Inventory (DCI) in an Italian Community Sample

ABSTRACT The Detachment and Compartmentalization Inventory (DCI) is a valid and reliable self-report instrument that assesses these two distinct forms of dissociative symptoms. However, there is limited research on the cross-cultural validation of the DCI. Therefore, this study aimed to develop an Italian translation of the DCI and examine its internal structure and psychometric properties (including internal consistency, convergent validity, and test-retest reliability) within an Italian-speaking community sample. The sample consisted of 1276 adults (887 females; mean age: 29.57 ± 10.96 years), who completed the DCI and other self-report measures evaluating dissociative experiences and childhood trauma. Confirmatory factor analyses supported the original two-factor model (χ2 169 = 1312.80, RMSEA = 0.073, 95%CI 0.069–0.077; CFI = 0.94; TLI = 0.94; SRMR = 0.04). Additionally, the DCI exhibited good internal consistency, test-retest reliability, and convergent validity with another measure of dissociation. The study also confirmed the association between DCI scores and the severity of childhood trauma. Finally, a Receiver Operating Characteristic (ROC) curve analysis demonstrated that the DCI effectively distinguishes individuals who screened positively for dissociative disorders. Overall, these findings indicate that the Italian translation of the DCI possesses satisfactory psychometric properties, suggesting its utility as a screening tool for assessing detachment and compartmentalization experiences.

Assessment of Empathy as a Prerequisite for Holistic Nursing: Psychometric Analysis of the Jefferson Scale of Empathy-Health Profession Students for Croatian BSc and MSc Nursing Students.

Purpose: To translate the original Jefferson Scale of Empathy-Health Profession Students version in a group of nursing students and asses its psychometrical characteristics according to the COnsensus-based Standards for the selection of health Measurement INstruments guidelines. Design: A descriptive cross-sectional study. Methods: The study included 345 bachelor's and master's students in the nursing degree program. Construct validity was tested by exploratory factor analysis using principal component analysis with varimax rotation. Convergent validity was tested using the Pearson correlation coefficient to test the relationship between empathy and emotional intelligence. The reliability of internal consistency was estimated using Cronbach's alpha. Findings: The final version of the 16-item scale with its three-factor structure has a high reliability with a Cronbach's alpha value of 0.86, and the Pearson correlation coefficient revealed a positive and significant relationship between emotional intelligence and the total score of the empathy scale and the three subscales. Conclusion: The contribution of the study is significant as the instrument is qualitatively validated and its content is clinically and educationally important for understanding the concept of empathy, especially in the education of nursing students. The correct assessment of empathy contributes to a better understanding and implementation of the components of holistic care.

Slovenian version of the Stroke and Aphasia Quality of Life Scale 39-Generic Version (SAQOL-39g): Psychometric properties

ABSTRACT Purpose Aphasia, which is one of the most common consequences of stroke, has severe impact on everyday life. Quality of life in persons with aphasia changes dramatically. In the recent years, there has been a lot of interest in assessing health-related quality of life, but few questionnaires are adapted to people with aphasia (PwA). The Stroke Aphasia Quality of Life-39 scale (SAQOL-39) Generic Version is suitable for people with and without aphasia. Our study examined the reliability and validity of a translation of the SAQOL-39 g into Slovenian in Slovenian-speaking PwA. Methods Translation, back-translation from English into Slovenian language was performed. Seventy-three PwA with broad range of severity and times post-onset of stroke were included in the study of psychometric properties of the Slovenian translation. Results The psychometric properties in Slovenian version were quite similar to other languages, with high internal consistency and test-retest reliability (Cronbach alpha > 0.94; ICC ≥0.99). Conclusion The Slovenian translation of the SAQOL-39 g is a valid and reliable measure of quality of life in PwA. It can be clinically used as an additional tool for goal setting in Slovenian PwA.

Translation and validation of ageism scale for dental students into Malay language.

Identifying ageism among dental students is essential in gerodontology courses. This study aimed to perform a preliminary validation of a Malay version of the ageism scale for dental students (ASDS-My). The 27-item ASDS were translated into Malay language and completed by 168 dental students. Exploratory factor analysis (EFA) with Promax rotation, Polychoric Correlation Matrix and Principal Axis Factoring was conducted. Internal consistency reliability and discriminative validity were analysed. Criterion validity was measured by comparing ASDS-My with Fraboni Scale of Ageism (FSA). A Kaiser-Meyer-Olkin of 0.612 and a Bartlett's Test of Sphericity yielding p<.001 confirmed the adequate factorability. EFA revealed a 15-items scale distributed into five-factors explaining 54.5% of overall variance, with acceptable reliability. The two factors involved cost-benefit of dental treatment on older patients and challenges during medical history taking. The third, fourth and fifth factors explained attitude towards older patients, negative views of older patients and exposure of dental students to Gerodontology training and experiences respectively. Most factors were significantly positively related to FSA. Discriminative validity revealed significant differences for gender, place of stay and year of study. Preliminary validation of the ASDS-My produced a five-factors 15-items scale with acceptable validity and reliability.

Development and Factor Structure of Problematic Multidimensional Smartphone Use Scale

AbstractLiving in an intensifying technological and digital environment makes people more engaged with smartphones and related internet platforms. Alongside its highly debated advantages and disadvantages, modern smartphone use is a global phenomenon which has been mainly debated within the context of cultural and technology relationships which also influence cross-cultural activities. Focusing on one of the modern factors (i.e., smartphone use) that impact human behavior, this article presents the development of a measure of the Multidimensional Smartphone Use Scale (MSUS) and tests its factor structure to offer a scale that covers smartphone-related problems from a broader perspective. Using an online survey, a total of 514 participants took part in the current study. The scale was developed to measure a multidimensional conception of smartphone use-related problems and behavioral disorders including nomophobia, ringxiety, textiety, and phubbing which were supported with exploratory and confirmatory factors analyses. The MSUS indicated good internal consistency reliability ranging from α = .75 to α = .89. This article presents the preliminary evidence regarding the reliability and validity of the MSUS which can be used in a wide range of settings to measure maladaptive modes of smartphone use and related behaviors.

Cross-cultural adaptation and psychometric properties of the Thai version of the patient-reported outcomes measurement information system short form– depression 8a in individuals with chronic low back pain

BackgroundThe study aimed to cross-culturally adapt the Patient-Reported Outcomes Measurement Information System Short Form v1.0 - Depression 8a (PROMIS SF v1.0 - Depression 8a) into Thai and evaluate its psychometric properties in individuals with chronic low back pain (CLBP).MethodsThe PROMIS SF v1.0– Depression 8a was translated and cross-culturally adapted into Thai using the Functional Assessment of Chronic Illness Therapy translation methodology. Two hundred and sixty-nine individuals with CLBP completed the Thai version of PROMIS SF v1.0– Depression 8a (T-PROMIS-D-8a) scale and a set of measures assessing validity criterion domains. Structural validity, internal consistency, and test-retest reliability at a 7-day interval of the T-PROMIS-D-8a scale were computed and its construct validity was evaluated by computing correlations with the Thai version of Patient Health Questionnaire-9 (T-PHQ-9), Numeric Rating Scale of pain intensity (T-NRS), and Fear Avoidance Beliefs Questionnaire (T-FABQ).ResultsData from 269 participants were analyzed. Most participants were women (70%), and the sample had a mean age of 42.5 (SD 16.6) years. The findings supported the unidimensionality, internal consistency (Cronbach’s alpha = 0.94), and test-retest reliability (ICC [2,1] = 0.86) of the T-PROMIS-D-8a. A floor effect was observed for 16% of the sample. Associations with the T-PHQ-9, T-NRS, and T-FABQ supported the construct validity of the T-PROMIS-D-8a.ConclusionsThe T-PROMIS-D-8a was successfully translated and culturally adapted. The findings indicated that the scale is reliable and valid for assessing depression in Thai individuals with CLBP.

Translation and Validation of Tamil Version of Fatigue Severity Scale (FSS) in Individuals with Rheumatoid Arthritis

Background: Fatigue has a significant negative impact on individuals with Rheumatoid Arthritis (RA). Fatigue Severity Scale (FSS) is the most widely used tool to assess fatigue severity which is a common problem in RA. Availability of FSS in local vernacular language could add more value and the study aims to construct the Tamil version of the FSS and validate it among patients with RA. Methodology: The study was conducted in 2 phases. In phase I, the English version of FSS was translated into Tamil by following the Linguistic Guidelines by mapi eprovide. In Phase II – Validation of Tamil version of FSS was carried out in 50 patients of RA by establishing; Test-retest reliability, Internal consistency, Content validity; and Convergent validity in comparison with HAQ-DI and SF-12 Results: The initial testing between Tamil FSS with English version revealed an intraclass correlation coefficient (ICC) (0.821) and α(0.902). The content validity was established by Cohen’ kappa agreement k which is &gt;80% with a significance &lt;0.004, which shows Good substantial agreement between raters. FSS showed strong positive correlation with HAQ-DI (&gt;0.0005) and negative correlation with SF-12 (&gt;0.0005). The scale demonstrated excellent internal consistency ( α = 0.972) and test-retest reliability (ICC = 0.93). Conclusions: The validated Tamil version demonstrated excellent content validity as well as good internal consistency and test-retest reliability, would be a useful instrument for clinical practice and research. It can be recommended for the assessment of Fatigue severity among Tamil-speaking population with RA.

Psychometric Properties of the Persian Version of the Yale Food Addiction Scale 2.0 (P-YFAS 2.0) in an Iranian Clinical Sample

Background: The aim of this study was to assess the psychometric aspects of Persian version of Yale Food Addiction Scale 2.0 (YFAS 2.0) and the prevalence of Food Addiction (FA) among Iranian obese population seeking bariatric surgery.&#x0D; Methods: In this cross-sectional study, psychometric aspects of the YFAS 2.0 including validity and reliability were assessed. Convergent and discriminant validity of the YFAS 2.0 was evaluated using Eating Disorder Inventory-3, Referral form (EDI-3 RF), Dutch Eating Behavior Questionnaire (DEBQ), Difficulties in Emotion Regulation Scale (DERS), and Barratt Impulsiveness Scale (BIS-15) and reliability of the scale was examined by test-retest analysis and internal consistency.&#x0D; Results: Among 124 patients (48.6%) who met FA criteria, 2 patients (1.6%) received a mild, 12 (9.6%) a moderate, and 110 (88.7%) a severe FA diagnosis. FA was more prevalent and severe in females, unmarried individuals, unemployed patients, and those with higher Body Mass Index (BMI) or binge eating disorder/bulimia nervosa diagnoses. Reliability analysis showed high internal consistency (Cronbach’s α = 0.89) and test-retest reliability (ICC = 0.88). Content validity was 0.8 or higher in terms of convergent validity. Except for one criterion, a one-factor structure was confirmed for the P-YFAS 2.0 (above 0.42). FA prevalence was higher in participants with BED or bulimia nervosa, and FA severity was correlated with scores on measures of impulsivity, emotion regulation difficulties, eating behaviors and psychopathology.&#x0D; Conclusion: These findings support the reliability and validity of the P-YFAS 2.0 in assessing FA as defined by Diagnostic and Statistical Manual of Mental Disorders-fifth (DSM-5). The high rate of FA identified highlights the need for targeted interventions in this clinical population.

Validation of the Hungarian Version of the Prolapse and Incontinence Knowledge Questionnaire (PIKQ)

ObjectiveThe Prolapse and Incontinence Knowledge Questionnaire (PIKQ) is a self-administered, reliable and valid instrument which assess knowledge regarding urinary incontinence and pelvic organ prolapse. There is no validated Hungarian version of this questionnaire; therefore the aim of this study was to develop a reliable, valid and culturally sensitive Hungarian version of the PIKQ. Study DesignA cross-sectional study was conducted from March to October 2022 with a sample of 459 women. The PIKQ, which consists of the urinary incontinence and pelvic organ prolapse scales, was translated into Hungarian in accordance with international guidelines. The validity and reliability of the final version of the Hungarian PIKQ was evaluated using construct validity, comparison with known-groups, internal consistency and test-retest reliability. ResultsRegarding construct validity, all fit indices were found acceptable. Healthcare workers had significantly higher knowledge about urinary incontinence and pelvic organ prolapse (p<0.001) compared to women who had not worked in a medical field. The Hungarian PIKQ had an adequate internal consistency with Cronbach alpha of 0.785 for the urinary incontinence scale and 0.826 for the pelvic organ prolapse scale. The correlation coeffcients between the test and retest was 0.931 for the urinary incontinence scale and 0.964 for the pelvic organ prolapse scale. ConclusionThe Hungarian version of the PIKQ is a reliable and valid tool to measure the level of knowledge about urinary incontinence and pelvic organ prolapse among Hungarian speaking women.

Social Variables and Maladaptive Behaviours among Secondary School Students in Akwa Ibom State, Nigeria

The study examined Social variables and Maladaptive behaviour of public senior secondary school students in Akwa Ibom State, Nigeria Three research questions were formulated and three hypotheses were stated in their null form and tested with appropriate statistics at a .05 level of significance. The descriptive survey design was adopted for the study. The population of the study comprised 54,216 senior secondary two (SS2) students in all 235 public secondary schools in Akwa Ibom State, Nigeria. Nwana’s sampling formula was used to select 20% of students from nineteen (9) public secondary schools. The researcher made use of a questionnaire entitled (FVSDBTQ) to obtain data from respondents. The instrument was validated by experts in the sociology of Education and Measurement and Evaluation from the Department of Educational Foundations, Guidance and Counseling, University of Uyo, Uyo. Cronbach Apha analysis for internal consistency reliability of the instrument yielded a coefficient of .96. Research questions were answered using mean and standard deviation while the hypotheses were tested using independent t-test and ANOVA. The study revealed that social variables differ in terms of the maladaptive behaviour of secondary school students in Akwa Ibom State, Nigeria. The independent t-test and ANOVA of the hypotheses indicated significant differences in students’ maladaptive behaviour based on family discipline, family emotional climate and parent-child relationship. It was, therefore, concluded that social variables differ significantly based on students’ maladaptive behaviour in Akwa Ibom State, Nigeria. The researcher made some useful recommendations which include: parents should also take the discipline of their children seriously; parents should show a good example for their children to emulate and parents should also develop a healthy relationship with their children to help them develop good moral behaviour among other recommendations.

Self-assessment questionnaire development for soft skills competency and core value evaluations

Soft skills play a vital role for providing excellent customer service in the healthcare setting. This study aims to develop and assess the instrument validity and reliability before measuring the levels of soft skills competency and core value internalization on staffs at the Sultan Ahmad Shah Medical Centre @International Islamic University Malaysia (SASMEC@IIUM). A self-assessment questionnaire was developed through three phases. The first phase involved reviewing and identifying relevant literatures and existing soft skills assessment instruments through bibliographic searches and expert consultations. A conceptual model was then established based on the selected conceptual frameworks after determining all relevant soft skill domains. The second phase involved generating relevant items, removing duplicate or irrelevant items, and appraising the content validity by three experts. The third phase was data collection, wherein the finalized instrument was distributed to 32 staff of SASMEC@IIUM via google forms. The instrument reliability was investigated through internal consistency reliability or Cronbach’s alpha, with all items, except for the construct ‘gratitude’, achieving acceptable values by exceeding the threshold value of 0.7. Subsequently, two gratitude items were removed from the questionnaire. The current instrument and theoretical framework employed in the self-assessment questionnaire development are valid and reliable for the actual application.

Reliability and Validity of the Minimum Data Set 3.0 Standardized Self-Care and Mobility Data Elements Among Long-Stay Nursing Home Residents.

To assess the reliability and validity of a subset of the Minimum Data Set (MDS) 3.0 Section GG data elements (i.e., standardized self-care, mobility) among 147 long-stay nursing home residents in seven nursing homes in five states. Trained clinicians assessed residents' functional abilities using select Section GG items and Section G activities of daily living items. We examined the reliability and construct validity of the data using Cronbach's alpha, correlations between Section G and Section GG items, confirmatory factor analysis (CFA), and Rasch measurement analysis. We observed acceptable internal consistency values for all (0.98), self-care (0.93), and mobility (0.98) standardized items. Correlations between conceptually related Section G and Section GG items ranged from -0.53 to -0.84. CFA findings found acceptable values for all fit indices. Rasch analysis showed most items had acceptable fit statistics, except for the easiest and most difficult activities. These findings establish the feasibility of data collection, internal consistency reliability, and construct validity of the selected Section GG items among long-stay nursing home residents. Use of the same standardized data elements in post-acute and long-term care populations can support improved coding of function and enhance our understanding of resident functioning.

Validation of the brief version of the Susceptibility to Persuasion-II scale and evaluation of measurement invariance across age and gender in the Canadian general population

Measurement tools that can assess personality traits rendering people more susceptible to engagement with and compliance in scams can help identify at-risk populations. The brief, 30-item version of the Susceptibility to Persuasion-II (StP–II–B) scale is a recently developed instrument for assessing 10 personality traits that play a role in scam compliance; however, psychometric evidence supporting the use of this scale is limited. This study aimed to validate the StP–II–B by examining its internal consistency reliability, factor structure, as well as age- and gender-related measurement invariance with a sample of 1287 Canadians aged 16 years and older. Confirmatory factor analysis supported a 10-factor structure identified in previous research. Good internal consistency reliability was obtained for each of the 10 subscales. This 10-factor structure was found to be invariant across age and gender at configural, metric, and scalar levels, suggesting that the StP–II–B was conceptualized in the same way across age and gender and that meaningful comparisons of factor scores could be made. Age and gender differences were found in most factors, with younger individuals and men scoring higher than older individuals and women. This study supports the use of the StP–II–B as a valid and reliable scale for measuring personality traits associated with scam compliance in the Canadian general population and offers insights into age and gender cohorts that may be at higher risk of scam victimization.

Development and validity of an intermediate conceptual measurement (ICM) -based measurement tool for the nursing professional values of undergraduate students

BackgroundNursing professional values are the foundation of nursing practice. There has been no research to develop an instrument to measure professional values in nursing based on intermediate conceptual measurement theory. ObjectivesTo develop an ICM-based measurement tool for the nursing professional values of undergraduate students. DesignA cross-sectional study. MethodsThe Nursing Professional Values-Intermediate Conceptual Measurement (NPV-ICM) was developed using the steps of Cunningham's process to generate questionnaire items. The tool was devised in three stages: identifying the intermediate concepts, developing stories reflecting the intermediate concepts and setting up options for action and justification in the stories and setting up scoring criteria for the measurement tool. The tool was tested through internal consistency reliability, content validity and calibration correlation validity. ResultsThis study resulted in five nursing professional values situational stories containing five themes (care, altruism, responsibility, respect and justice) respectively. Each situational story contained a varying number of action options and justification options, totalling 72 Richter 5 level options and 20 ranked items. Reliability and validity were found to be good, with a total Cronbach's α of 0.93 and Cronbach's α of 0.75–0.80 for each situational story and calibrated correlational validity was found to correlate significantly between the total Nursing Professional Values Scale Revised (NPVS-R) scores and the NPV-ICM. ConclusionsThe NPV-ICM created in this study possesses high reliability and validity. It alters the values perception research, moving from abstract conceptual measurements to measurements of particular values actions and justifications for participation in activities. And the study presents preliminary evidence supporting the reliability of the NVP-ICM as a measure of professional values.

Psychometric properties of the Buss-Perry Aggression Questionnaire-short form among law enforcement officers.

Repeatedly capturing national headlines, excessive law enforcement officer (LEO) use of force in critical incident encounters is one of the most divisive human rights issues in the United States. Valid and reliable measures of potential precursors to LEO excessive use of force, such as aggression, are needed. The Buss-Perry Aggression Questionnaire-short form (BPAQ-SF) is a validated measure of aggression across various populations; however, evaluation of this easily administered measure in high-stress, frontline populations such as LEOs is limited. The primary goal of this study was to evaluate the validity, reliability, and sensitivity to change the BPAQ-SF in a sample of LEOs. A confirmatory factor analysis suggested that the hierarchical solution provides a mixed fit to the data:SBχ²(25.84) = 62.50, p = .0001; comparative fit index = .94, non-normed fit index = .92, root mean square error of approximation = .19 (90% confidence interval = .17-.21), standardized root mean squared residual = .08. The BPAQ-SF demonstrated good internal consistency (α = .84) and test-retest reliability (r = .86), correlations in the expected direction with predictors of and buffers against aggression, and sensitivity to change among LEOs who participated in an intervention targeting aggression. Results support and extend previous findings suggesting that the BPAQ-SF is a valid and reliable measure of aggression among LEOs.

Development and Psychometric Validation of a Patient-Reported Outcome Measure to Assess the Signs and Symptoms of Chronic Hand Eczema: The Hand Eczema Symptom Diary (HESD).

Chronic Hand Eczema (CHE) is an inflammatory skin disease of the hands. The Hand Eczema Symptom Diary (HESD) is a new patient-reported outcome measure of worst severity of core CHE signs/symptoms. This study aimed to evaluate content and psychometric validity of the HESD. The HESD was developed based on the literature and concept elicitation interviews. Qualitative cognitive debriefing interviews were conducted with CHE patients to assess relevance and understanding of items, response options and recall period. Psychometric properties of the HESD (item performance, dimensionality, reliability, validity, responsiveness and estimation of meaningful change thresholds) were then assessed, first using data from a phase 2b trial (NCT03683719), and confirmed using data from the first 280 participants completing the 16-week treatment phase of a phase 3 trial (NCT04871711). Cognitive debriefing supported item refinement and removal of items and confirmed all items were well understood and relevant to patients. Item properties and dimensionality analyses in the phase 2b data supported removal of additional items, resulting in the 6-item HESD included in the phase 3 trial. Unidimensionality was supported by inter-item correlations (all > 0.70) and Rasch analysis. Internal consistency (Cronbach's alpha = 0.96) and test-retest reliability (IntraclassCorrelationCoefficient > 0.89) results were very strong. Construct validity was supported by moderate correlations with concurrent measures (0.53-0.64) and significant differences between severity groups (p < 0.001). Large effect sizes for mean change scores in participantsthat improved and significant differences between change groups indicatedthe ability to detect change. Anchor-based analyses supported within-individual responder definitions of ≥ 4-points for improvements in 7-day average HESD scores. The HESD is the first CHE-specific, patient-reported outcome measure of CHE signs/symptoms developed and validated in line with regulatory guidance. This article provides evidence of strong content validity and psychometric validity and shows improvements of ≥ 4 points on 7-day average HESD scores represent clinically meaningful, important changes. NCT03683719, NCT04871711.

Development, reliability, and validity of the mobility assessment scale in hospitalized patients (HMob)

BackgroundExisting mobility scales for hospitalized patients do not include assessment of tasks for the right and left side, ability to transfer from sitting to lying and from standing to sitting, ability to climbing steps and pick up an object from the floor in the same instrument. ObjectiveEvaluate the reliability and validity of the hospital mobility assessment scale (HMob) according to the Consensus-based standards for the selection of health measurement instruments (COSMIN). MethodsStudy conducted in three inpatient units (cardiology, neurology, and gastrohepatology) and one adult intensive care unit in a hospital. Patients of both sexes were included; age >18 years; collaborative and who obeyed commands, with different medical diagnoses and clinical release to leave their bed (provided by the doctor). Special populations such as those with burns and orthopedics were excluded. ResultsThe sample consisted of 130 patients; 20 from the pilot study and 110 to assess the clinimetric properties of the HMob. Cronbach alpha coefficient was 0.949. Relative intra- (A1-A2) and inter-rater (A1-B; A2-B) reliability was excellent (A1-A2: ICC = 0.982, p-value < 0.0001; A1-B: ICC = 0.993, p-value < 0.0001; A2-B: ICC = 0.986, p-value < 0.0001.) The convergent criterion validity of HMob in relation to the ICU Functional Status Score was 0.967 (p-value < 0.0001) and for Functional Independence measure (MIF) was 0.926 (p-value < 0.0001). ConclusionThe HMob scale showed excellent internal consistency, intra- and inter-rater reliability, and concurrent validity in the motor domain, which suggests that it can be used in daily practice to measure mobility in hospitalized patients.

Psychometric evaluation of the Polish version of the Questionnaire of Attitudes of Healthcare Workers towards Reporting of Clinical Adverse Events (P-RoCAES)

Abstract Aim. The purpose of the study was psychometric evaluation of the Polish version of the Questionnaire of Attitudes of Healthcare Workers towards Reporting of Clinical Adverse Events (P-RoCAES), based on an adaptation of the Reporting of Clinical Adverse Events Scale (RoCAES) by Wilson B., Bekker H.L., Fylan F. Material and methods. A total of 101 participants took part in the study, 41.4% of whom were internal medicine nurses, the remaining percentage were nursing students. In addition to the P-RoCAES, the Author’s Survey Questionnaire, the Justice Sensitivity Inventory, the Moral Feelings Scale, the Perceived Stress at Work Scale were used. Results. P-RoCAES reliability (internal consistency: Cronbach’s alpha 0.82; McDonald’s omega 0.80) and theoretical relevance for questions from the Author’s Survey Questionnaire were found. Convergent relevance with sensitivity to justice, feelings in moral situations, work stress perception were not proven. Confi rmatory factor analysis did not provide a reinforcement of the 5-dimensional factor structure of the original RoCAES. Conclusions. The P-RoCAES achieved satisfactory psychometric properties in validation to Polish conditions, enabling to be used in research of attitudes towards adverse events among medical professionals and students, in order to educate and promote reporting culture for maintaining patient safety in healthcare. Despite possible limitations, the P-RoCAES should be considered an objective, valid, reliable tool.
